乙醇与冰乙酸用量对混晶TiO2光催化性能影响
Effect of Ethanol and Acetic Acid Dosages on Photocatalytic Property of Mix-phase TiO2
摘要
Abstract
In the route of sol-gel process,different amounts of ethanol and acetic acid were selected,and the anatase/rutile mixed-phase TiO2powders were prepared by thermal treatment of the precursor at 540℃for 2 h.The crystal structure, surface morphology and element composition of the samples were characterized by XRD,SEM and EDS, respectively.The photocatalytic property of the sample powders were evaluated by the degradation rate of rhodamine B.The results show that the samples are mixed crystal structure, and the amount of ethanol and glacial acetic acid have an effect on the content of anatase/rutile.When the amount of ethanol is 90 mL and the amount of glacial acetic acid is 5 mL,the TiO2powder possesses the highest photocatalytic efficiency.After 3 h,the degradation rate of rhodamine B is 83.9%,and the reaction rate constant k is 0.00982 min -1.关键词
